    Notes:
    ~~~~~~
    (1) Still have problem with tracking mount loosing azimuth position which
        slows operations somewhat as I have to reset the mount on a known
        bright star before every satellite transit . Changed lubrication grease
        but no effect so looks like something more serious.
    
    (2) USA 144 appears to have changed optical characteristics. Formerly had
        a long period variation but tonight was rapidly flickering the entire
        pass.
    
    (3) First hours tracking was difficult as I had to track blind on
    predictions
        and occasionally see the satellite through thin cloud or in a clear
        spot so I had to get positions when I saw the satellite.
    
    (4) Weather bad at present - my rainy season has finally struck but about
        two months late!
    
    Cheers
    Greg
